Learn More →For San Marcos, California homeowners dealing with wildfire smoke and seasonal allergens, indoor air quality isn’t just a comfort issue — it’s a health priority. The EPA consistently ranks indoor air pollution among America’s top five environmental health risks, and San Marcos’s Mediterranean climate makes the situation more urgent. D&D Air Duct Cleaning provides professional Duct Repair that addresses the root cause: contaminated air duct system that recirculates pollutants through your home thousands of times.

According to NADCA, the average six-room home generates 40 pounds of dust per year. The EPA estimates Americans spend 90% of their time indoors. For San Marcos families, that means breathing recirculated air that passes through contaminated ducts thousands of times. In California’s Mediterranean climate, moisture and temperature conditions accelerate contaminant buildup significantly compared to other regions.
